  • News

Do take a look at all these blog posts as they showcase most =agent-shell= features.

  • Related projects

=agent-shell= relies on [[https://github.com/xenodium/acp.el][acp.el]] to communicate with agents via ACP ([[https://agentclientprotocol.com/][Agent Client Protocol]]).

We now have a handful of additional packages to extend the =agent-shell= experience:

  • Articles
  • Icons

Thanks to [[https://github.com/lobehub/lobe-icons][Lobe Icons]] for the lovely icons.

  • Setup

** External dependencies

*** Claude Agent SDK

For Anthropic's [[https://code.claude.com/docs/en/overview][Claude Agent]] (formerly known as the Claude Code), follow [[https://github.com/agentclientprotocol/claude-agent-acp][claude-agent-acp instructions]], typically something like:

#+begin_src bash npm install -g @agentclientprotocol/claude-agent-acp #+end_src

Note: The =-g= flag is required to install the binary globally so it's available in your PATH. After installation, verify it's available by running =which claude-agent-acp= in your terminal.

Optionally: You may also need [[https://code.claude.com/docs/en/overview][Claude Agent]] itself if you want to use a Claude subscription (run the CLI outside of Emacs at least once to log in to your subscription and then use =agent-shell= from Emacs). Follow Claude Agent's [[https://code.claude.com/docs/en/overview#get-started][get started]] for installation.

*** Codex

For OpenAI's Codex, install [[https://github.com/agentclientprotocol/codex-acp][@agentclientprotocol/codex-acp]] (=npm install -g @agentclientprotocol/codex-acp=) and ensure the =codex-acp= executable is in PATH.

*** Gemini CLI

For Google's [[https://github.com/google-gemini/gemini-cli][Gemini CLI]], be sure to get a recent release supporting the =--experimental-acp= flag.

*** Goose

For Goose CLI, install [[https://goose-docs.ai/docs/getting-started/installation][goose]] and ensure the =goose= executable is in PATH.

*** Grok Build (xAI)

For [[https://docs.x.ai/docs/overview][Grok Build]], install the Grok CLI so =grok= is on =PATH= (the installer typically puts it at =/.grok/bin=). Authenticate once via the CLI login flow (credentials live in =/.grok/auth.json=).

Grok Build speaks ACP over stdio:

#+begin_src bash grok agent stdio #+end_src

Optional flags (set via =agent-shell-xai-acp-command=):

#+begin_src bash grok agent -m grok-build stdio grok agent --always-approve stdio #+end_src

See also the [[https://zed.dev/acp/agent/grok-build][Zed ACP registry listing]] for Grok Build.

*** Cursor

For Cursor agent, install the official [[https://cursor.com/docs/cli][Cursor CLI]] and ensure the =agent= executable is in PATH. =agent-shell= uses its official ACP server (=agent acp=).

A recent Cursor CLI is required (the =acp= subcommand was added in 2026). Older CLIs won't expose =agent acp=.

*** Kimi Code CLI

For Kimi Code CLI, install with:

#+begin_src bash curl -L code.kimi.com/install.sh | bash #+end_src

See https://www.kimi.com/code for details.

*** CodeBuddy

For CodeBuddy agent, install the CodeBuddy CLI and ensure ACP mode is available. For example:

#+begin_src bash codebuddy --acp #+end_src

See https://www.codebuddy.ai/docs/zh/ide/Getting-Started/Installation for details.

*** Kiro CLI

For Kiro CLI, install with:

#+begin_src bash curl -fsSL https://cli.kiro.dev/install | bash #+end_src

See https://kiro.dev/docs/cli/acp/ for details.

*** Qwen Code

For Qwen Code, install with:

#+begin_src bash npm install -g @qwen-code/qwen-code@latest #+end_src

See https://github.com/QwenLM/qwen-code for details.

*** Auggie

For Auggie CLI, install with:

#+begin_src bash npm install -g @augmentcode/auggie #+end_src

See https://docs.augmentcode.com/cli/overview for details. *** Mistral Vibe

For Mistral Vibe, install with:

#+begin_src bash uv tool install mistral-vibe #+end_src

See https://github.com/mistralai/mistral-vibe for details.

*** Factory Droid

For Factory Droid, install Droid:

#+begin_src bash curl -fsSL https://app.factory.ai/cli | sh #+end_src

See https://factory.ai for details.

*** Pi

For Pi coding agent, install the =pi-acp= adapter:

#+begin_src bash npm install -g pi-acp #+end_src

See https://github.com/svkozak/pi-acp for details. *** Oh My Pi (=omp=)

For the =omp= agent, install with:

#+begin_src bash bun install -g @oh-my-pi/pi-coding-agent #+end_src

See https://github.com/can1357/oh-my-pi for details.

*** Antigravity

For Antigravity, download the =agy_acp_server= binary for your platform from the [[https://github.com/agentclientprotocol/registry/tree/main/antigravity-acp][ACP registry entry]] and make sure it's on your =PATH= (or set =agent-shell-antigravity-acp-command= to an absolute path).

Alternatively, you can bootstrap the antigravity tool with the following function:

#+begin_src emacs-lisp (defun agent-shell-antigravity-bootstrap (&optional force) "Download and install the latest Antigravity ACP server binary." (interactive "P") (let* ((arch (pcase (car (split-string system-configuration "-")) ((or "x86_64" "amd64") "x86_64") ((or "aarch64" "arm64") "aarch64") (a a))) (os (pcase system-type ('darwin "darwin") ('windows-nt "windows") (_ "linux"))) (platform (format "%s-%s" os arch)) (install-dir (agent-shell-cache-dir "antigravity" platform)) (bin-name (file-name-nondirectory (car agent-shell-antigravity-acp-command))) (bin-path (expand-file-name bin-name install-dir))) (unless (and (not force) (file-executable-p bin-path)) (message "Antigravity: bootstrapping server for %s..." platform) (make-directory install-dir t) (let* ((reg-url "https://raw.githubusercontent.com/agentclientprotocol/registry/main/antigravity-acp/agent.json") (reg (with-temp-buffer (url-insert-file-contents reg-url) (json-parse-buffer :object-type 'alist))) (archive-url (map-nested-elt reg `(distribution binary ,(intern platform) archive))) (zip (expand-file-name "server.zip" install-dir))) (url-copy-file archive-url zip t) (call-process "unzip" nil nil nil "-o" "-q" zip "-d" install-dir) (delete-file zip) (set-file-modes bin-path #o755))) (setq agent-shell-antigravity-acp-command (cons bin-path (cdr agent-shell-antigravity-acp-command))) (message "Antigravity: using ACP server at %s" bin-path) bin-path)) #+end_src

See https://antigravity.google/docs/ide/extensions for details.

*** Opencode + local ollama models

For opencode coding agent, install with:

#+begin_src bash curl -fsSL https://opencode.ai/install | bash #+end_src

See https://opencode.ai/ for details.

For local ollama models, sudo permission is needed to initialize ollama.service. The following will install ollama and a local Qwen2.5:7b model.

#+begin_src bash curl -fsSL https://ollama.com/install.sh | sh ollama pull qwen2.5:7b #+end_src

If you are behind a network proxy, ollama pull will timeout. You then need to add proxy settings inside /etc/systemd/system/ollama.service

See https://ollama.com/ for details

** Installation

=agent-shell= is powered by built-in =comint-shell=, via [[https://github.com/xenodium/shell-maker][shell-maker]], available on [[https://melpa.org/#/shell-maker][MELPA]].

Both [[https://melpa.org/#/agent-shell][agent-shell]] and its dependency [[https://melpa.org/#/acp][acp.el]] are now available on MELPA.

You can install via:

#+begin_src emacs-lisp (use-package agent-shell :ensure t :ensure-system-package ;; Add agent installation configs here ((claude . "brew install claude-code") (claude-agent-acp . "npm install -g @agentclientprotocol/claude-agent-acp"))) #+end_src

This will automatically install the required dependencies ([[https://melpa.org/#/acp][acp.el]] and [[https://melpa.org/#/shell-maker][shell-maker]]).

*** Optional: image utilities

Pasting images from the clipboard (=agent-shell-send-clipboard-image= or =yank= or =C-y=) and capturing screenshots (=agent-shell-send-screenshot=) rely on external tools. Install the ones for your platform:

| Platform | Clipboard paste | Screenshot capture | |-----------------+------------------------------------------+------------------------------| | macOS | =brew install pngpaste= | =screencapture= (preinstalled) | | Linux (Wayland) | =wl-paste= (e.g. =apt install wl-clipboard=) | =import= (from ImageMagick) | | Linux (X11) | =apt install xclip= | =import= (from ImageMagick) | | Windows | =powershell= | (not bundled) |

Handlers are detected at runtime via =executable-find=. See =agent-shell-clipboard-image-handlers= and =agent-shell-screenshot-command= to customize.

*** Doom Emacs

If you are using Doom Emacs and would like to use the =package!= macro:

#+begin_src emacs-lisp (package! shell-maker) (package! acp) (package! agent-shell) #+end_src

Run =doom sync= and restart.

Include =require= before configuration:

#+begin_src emacs-lisp (require 'acp) (require 'agent-shell) ;; rest of config... #+end_src

** Configuration

Configure authentication for the agent providers you want to use.

*** Environment variables

Pass environment variables to the spawned agent process by customizing the agent-shell-*-environment variable with agent-shell-make-environment-variables. The helper accepts key/value pairs and exports them when the agent starts.

#+begin_src emacs-lisp (setq agent-shell-anthropic-claude-environment (agent-shell-make-environment-variables "ANTHROPIC_API_KEY" (auth-source-pass-get 'secret "anthropic-api-key") "HTTPS_PROXY" "http://proxy.example.com:8080")) #+end_src

**** Inheriting environment variables

By default, the agent process starts with a minimal environment. To inherit environment variables from the parent Emacs process, use the :inherit-env t parameter in agent-shell-make-environment-variables:

#+begin_src emacs-lisp (setenv "ANTHROPIC_API_KEY" (auth-source-pass-get 'secret "anthropic-api-key"))

(setq agent-shell-anthropic-claude-environment (agent-shell-make-environment-variables :inherit-env t)) #+end_src

This ensures that environment variables like PATH, HOME, and others from your Emacs session are available to the agent process, while still allowing you to override or add specific variables.

**** Loading environment variables from files

You can load environment variables from .env files using the :load-env parameter. This supports both single and multiple files:

#+begin_src emacs-lisp ;; Load from a single .env file (setq agent-shell-anthropic-claude-environment (agent-shell-make-environment-variables :load-env "~/.env" "CUSTOM_VAR" "custom_value"))

;; Load from multiple .env files (setq agent-shell-anthropic-claude-environment (agent-shell-make-environment-variables :load-env '("~/.env" ".env.local") :inherit-env t)) #+end_src

The .env files should contain variables in the format KEY=value, with one variable per line. Comments (lines starting with #) and empty lines are ignored.

*** Anthropic Claude

#+begin_src emacs-lisp (setq agent-shell-anthropic-authentication (agent-shell-anthropic-make-authentication :login t)) #+end_src

For API key authentication:

#+begin_src emacs-lisp ;; With string (setq agent-shell-anthropic-authentication (agent-shell-anthropic-make-authentication :api-key "your-anthropic-api-key-here"))

;; With function (setq agent-shell-anthropic-authentication (agent-shell-anthropic-make-authentication :api-key (lambda () (auth-source-pass-get 'secret "anthropic-api-key")))) #+end_src

For OAuth token authentication (the =CLAUDE_CODE_OAUTH_TOKEN= we get from =claude setup-token=):

#+begin_src emacs-lisp ;; With string (setq agent-shell-anthropic-authentication (agent-shell-anthropic-make-authentication :oauth "your-oauth-token-here"))

;; With function (setq agent-shell-anthropic-authentication (agent-shell-anthropic-make-authentication :oauth (lambda () (auth-source-pass-get "secret" "anthropic-oauth-token")))) #+end_src

For alternative Anthropic-compatible API endpoints, configure via environment variables:

#+begin_src emacs-lisp (setq agent-shell-anthropic-claude-environment (agent-shell-make-environment-variables "ANTHROPIC_BASE_URL" "https://api.moonshot.cn/anthropic" "ANTHROPIC_MODEL" "kimi-k2-turbo-preview" "ANTHROPIC_SMALL_FAST_MODEL" "kimi-k2-turbo-preview")) #+end_src

#+begin_src emacs-lisp (setq agent-shell-google-authentication (agent-shell-google-make-authentication :login t)) #+end_src

For API key authentication:

#+begin_src emacs-lisp ;; With string (setq agent-shell-google-authentication (agent-shell-google-make-authentication :api-key "your-google-api-key-here"))

;; With function (setq agent-shell-google-authentication (agent-shell-google-make-authentication :api-key (lambda () (auth-source-pass-get 'secret "google-api-key")))) #+end_src

For Vertex AI authentication:

;; With function (setq agent-shell-openai-authentication (agent-shell-openai-make-authentication :api-key (lambda () (auth-source-pass-get 'secret "openai-api-key")))) #+end_src

*** Goose

By default, authentication is handled by Goose's built-in configuration. This needs no =agent-shell= configuration.

Optionally, pass an OpenAI API key from =agent-shell= instead:

#+begin_src emacs-lisp ;; With string (setq agent-shell-goose-authentication (agent-shell-make-goose-authentication :openai-api-key "your-openai-api-key-here"))

;; With function (setq agent-shell-goose-authentication (agent-shell-make-goose-authentication :openai-api-key (lambda () (auth-source-pass-get 'secret "openai-api-key")))) #+end_src

*** Qwen Code

For OAuth login-based authentication:

#+begin_src emacs-lisp (setq agent-shell-qwen-authentication (agent-shell-qwen-make-authentication :login t)) #+end_src

For an OpenAI-compatible provider (for example OpenRouter), pass the API key and set the base URL and model via =agent-shell-qwen-environment=:

#+begin_src emacs-lisp ;; With string (setq agent-shell-qwen-authentication (agent-shell-qwen-make-authentication :openai-api-key "your-openai-api-key-here"))

;; With function (setq agent-shell-qwen-authentication (agent-shell-qwen-make-authentication :openai-api-key (lambda () (auth-source-pass-get 'secret "openrouter-api-key"))))

(setq agent-shell-qwen-environment (agent-shell-make-environment-variables "OPENAI_BASE_URL" "https://openrouter.ai/api/v1" "OPENAI_MODEL" "x-ai/grok-4.3")) #+end_src

*** Cursor

By default authentication is handled externally: run =agent login= once outside Emacs and agent-shell uses that existing login (it sends no ACP authenticate request). This needs no configuration.

Optionally, have agent-shell drive login-based authentication (=cursor_login=):

#+begin_src emacs-lisp (setq agent-shell-cursor-authentication (agent-shell-cursor-make-authentication :login t)) #+end_src

For API key authentication (passed via the =CURSOR_API_KEY= environment variable):

#+begin_src emacs-lisp ;; With string (setq agent-shell-cursor-authentication (agent-shell-cursor-make-authentication :api-key "your-cursor-api-key-here"))

;; With function (setq agent-shell-cursor-authentication (agent-shell-cursor-make-authentication :api-key (lambda () (auth-source-pass-get 'secret "cursor-api-key")))) #+end_src

For auth token authentication (passed via the =CURSOR_AUTH_TOKEN= environment variable):

#+begin_src emacs-lisp (setq agent-shell-cursor-authentication (agent-shell-cursor-make-authentication :none t)) #+end_src

*** Auggie

For login-based authentication (default):

#+begin_src emacs-lisp (setq agent-shell-auggie-authentication (agent-shell-make-auggie-authentication :login t)) #+end_src

For no authentication (when using alternative authentication methods):

#+begin_src emacs-lisp (setq agent-shell-auggie-authentication (agent-shell-make-auggie-authentication :none t)) #+end_src

*** Mistral Vibe

For API key authentication:

#+begin_src emacs-lisp ;; With string (setq agent-shell-mistral-authentication (agent-shell-mistral-make-authentication :api-key "your-mistral-api-key-here"))

;; With function (reusing the API key configured in vibe) (setq agent-shell-mistral-authentication (agent-shell-mistral-make-authentication :api-key (lambda () (string-trim (shell-command-to-string "source ~/.vibe/.env; echo $MISTRAL_API_KEY"))))) #+end_src

*** Opencode + local ollama Qwen2.5

If opencode is not found by agent-shell, you can add it to the search path

#+begin_src emacs-lisp (use-package agent-shell :ensure t :config (add-to-list 'exec-path "~/.opencode/bin/")) #+end_src

To register the local Qwen2.5:7b model in opencode, two files needs to be edited:

/.config/opencode/opencode.json #+BEGIN_SRC js { "$schema": "https://opencode.ai/config.json", "permission": { "edit": "ask", "bash": "ask", "webfetch": "allow" }, "provider": { "ollama": { "name": "qwen2.5:7b", "npm": "@ai-sdk/openai-compatible", "options": { "baseURL": "http://localhost:11434/v1" }, "models": { "qwen2.5:7b": { "name": "Qwen2.5 7b" } } } } } #+END_SRC

and a dummy auth file /.local/share/opencode/auth.json

#+begin_src js { "ollama": { "type": "api", "key": "ollama" } } #+end_src

Huge thanks for /gdindi/ for finding and and describing this in https://github.com/xenodium/agent-shell/issues/526

*** Customizing Available Agents

By default, =agent-shell= includes configurations for all supported agents (Claude Agent, Gemini CLI, Codex, Goose, Grok Build, Cursor, CodeBuddy, Qwen Code, and Auggie). You can customize which agents are available through the =agent-shell-agent-configs= variable.

** Usage

*** Quick Start

=M-x agent-shell= - Start or reuse any of the known agents.

You can select and start any of the known agent shells (see =agent-shell-agent-configs=) via the =agent-shell= interactive command and enables reusing existing shells when available. With a prefix argument (=C-u M-x agent-shell=), it forces starting a new shell session, thus instantiating multiple agent shells.

*** Viewport interaction

Viewport is an alternative interface for composing prompts and viewing one request/response interaction at a time. It uses a separate buffer named after its associated shell with =" [viewport]"= appended. This buffer switches between =agent-shell-viewport-edit-mode= while composing and =agent-shell-viewport-view-mode= while reading.

Use one of these entry points to create and initialize the viewport buffer:

  • From an agent shell, type =C-c C-o= (=agent-shell-other-buffer=). At the live prompt this opens the viewport for composing; from an earlier interaction it opens the viewport at that interaction. Use =C-c C-o= again to return to the shell (=o= also works from viewport view mode).
  • Run =M-x agent-shell-prompt-compose= to compose in a dedicated buffer. With the default configuration, =C-c C-c= sends or queues the prompt and dismisses the compose window.
  • Set =agent-shell-prefer-viewport-interaction= to make the normal =agent-shell= command and related commands prefer the viewport:

#+begin_src emacs-lisp (setopt agent-shell-prefer-viewport-interaction t) #+end_src

In edit mode, =C-c C-c= sends or queues the prompt and switches to view mode when viewport interaction is preferred. Use =C-u C-c C-c= to send or queue while keeping the compose buffer open, =C-c C-p= to peek at the latest interaction without losing the draft, =C-c C-k= to cancel, and =C-c C-h= for help.

In view mode, use =r= to compose a reply, =R= to quote the response in a reply, =b= / =f= to move between interactions, =p= / =n= to move between items, =?= for help, and =q= to bury the viewport.

#+begin_quote [!NOTE]

Do not invoke =agent-shell-viewport-edit-mode= or =agent-shell-viewport-view-mode= directly in an agent shell buffer. They are major modes installed by the entry points above on the separate viewport buffer, not commands for converting the shell buffer. #+end_quote

*** Specific Agent Commands

Start a specific agent shell session directly:

  • =M-x agent-shell-antigravity-start-agent= - Start an Antigravity agent session
  • =M-x agent-shell-anthropic-start-claude-code= - Start a Claude Agent session
  • =M-x agent-shell-auggie-start-agent= - Start an Auggie agent session
  • =M-x agent-shell-codebuddy-start-agent= - Start a CodeBuddy agent session
  • =M-x agent-shell-openai-start-codex= - Start a Codex agent session
  • =M-x agent-shell-google-start-gemini= - Start a Gemini agent session
  • =M-x agent-shell-goose-start-agent= - Start a Goose agent session
  • =M-x agent-shell-xai-start-grok= - Start a Grok Build (xAI) agent session
  • =M-x agent-shell-cursor-start-agent= - Start a Cursor agent session
  • =M-x agent-shell-kiro-start-agent= - Start a Kiro CLI agent session
  • =M-x agent-shell-mistral-start-vibe= - Start a Mistral Vibe agent session
  • =M-x agent-shell-qwen-start= - Start a Qwen Code agent session
  • =M-x agent-shell-droid-start-agent= - Start a Factory Droid agent session
  • =M-x agent-shell-pi-start-agent= - Start a Pi coding agent session

*** Setting a default agent for all new shells

You can set a default agent to use for all new shells started via =agent-shell= like so:

#+begin_src emacs-lisp (setq agent-shell-preferred-agent-config (agent-shell-anthropic-make-claude-code-config)) #+end_src

Or by identifier (e.g. Grok Build):

#+begin_src emacs-lisp (setq agent-shell-preferred-agent-config 'grok-build) #+end_src

*** Configuring MCP servers

You can configure MCP servers directly via =agent-shell=. This allows you to avoid having to repeat configurations across every agent that you use.

#+begin_src emacs-lisp (setq agent-shell-mcp-servers '(((name . "notion") (type . "http") (headers . []) (url . "https://mcp.notion.com/mcp")))) #+end_src

** Running agents in Devcontainers / Docker containers (Experimental)

=agent-shell= provides rudimentary support for running agents and shell commands in containers.

Use =agent-shell-command-prefix= to prefix the command that starts the agent, or a shell command that should be run so it is executed inside the container.

*** Static command list

#+begin_src emacs-lisp (setq agent-shell-command-prefix '("devcontainer" "exec" "--workspace-folder" ".")) #+end_src

*** Function-based configuration

For dynamic per-agent containers, provide a function that takes the current agent-shell buffer and returns the command list:

#+begin_src emacs-lisp (setq agent-shell-command-prefix (lambda (buffer) (let ((config (agent-shell-get-config buffer))) (pcase (map-elt config :identifier) ('claude-code '("docker" "exec" "claude-dev" "--")) ('gemini-cli '("docker" "exec" "gemini-dev" "--")) (_ '("devcontainer" "exec" ".")))))) #+end_src

*** Per-session containers

You can use different containers for different shell sessions, even of the same agent type:

#+begin_src emacs-lisp (setq agent-shell-command-prefix (lambda (buffer) ;; Different container based on project (if (string-match "project-a" (buffer-name buffer)) '("docker" "exec" "project-a-dev" "--") '("docker" "exec" "project-b-dev" "--")))) #+end_src

Note that any =:environment-variables= you may have passed to =acp-make-client= will not apply to the agent process running inside the container. It's expected to inject environment variables by means of your devcontainer configuration / Dockerfile.

Next, set an =agent-shell-path-resolver-function= that resolves container paths in the local working directory, and vice versa. Agent shell provides the =agent-shell-devcontainer-resolve-path= function for use with devcontainers specifically: it reads the =workspaceFolder= specified in =.devcontainer/devcontainer.json=, or uses the default value of =/workspaces/= otherwise.

#+begin_src emacs-lisp (setq agent-shell-path-resolver-function #'agent-shell-devcontainer-resolve-path) #+end_src

Note that this allows the agent to access files on your local file-system. While care has been taken to restrict access to files in the local working directory, it's probably possible for a malicious agent to circumvent this restriction.

Optional: to prevent the agent running inside the container to access your local file-system altogether and to have it read/modify files inside the container directly, in addition to setting the resolver function, disable the "read/write text file" client capabilities:

#+begin_src emacs-lisp (setq agent-shell-text-file-capabilities nil) #+end_src

*** Data storage location

By default, agent-shell stores per-project data (transcripts, screenshots, etc.) under a =.agent-shell/= directory in the project root, and automatically adds that directory to =.gitignore= the first time it is created. This is a one-time operation: removing the entry from =.gitignore= will not cause it to be re-added. If you configure =agent-shell-dot-subdir-function= to store data outside the project =.agent-shell/= directory, agent-shell will not update the project's =.gitignore=.

You can change where this data is stored by setting =agent-shell-dot-subdir-function= to a custom function. The function receives one argument, SUBDIR (e.g. ="screenshots"=), and must return the absolute path to that subdirectory (without creating it).

For example, to store data under =user-emacs-directory= instead of the project tree, flattening the project path into a directory name:

#+begin_src emacs-lisp (defun my/agent-shell-dot-subdir (subdir) (let* ((cwd (string-remove-suffix "/" (agent-shell-cwd))) (sanitized (replace-regexp-in-string "/" "-" (string-remove-prefix "/" cwd)))) (expand-file-name subdir (locate-user-emacs-file (concat "agent-shell/" sanitized)))))

(setopt agent-shell-dot-subdir-function #'my/agent-shell-dot-subdir) #+end_src

This stores data at a path like =~/.emacs.d/agent-shell/home-user-src-myproject/screenshots/=.

*** Screenshots from clipboard

You can send a screenshot from your clipboard to your shell with =agent-shell-send-clipboard-image=. Call with =C-u= to =agent-shell-send-clipboard-image-to= to select from your shells. agent-shell relies on external programs to write an image from clipboard to file as configured in =agent-shell-clipboard-image-handlers=. Preconfigured handlers are

  • =wl-paste= for Wayland desktops,
  • =xclip= for Xorg,
  • =pngpaste= for MacOS.
  • =powershell= for Windows.

*** Inhibiting minor modes during file writes

Some minor modes (for example, =aggressive-indent-mode=) can interfere with an agent's edits. Agent Shell can temporarily disable selected per-buffer minor modes while applying edits.

#+begin_src emacs-lisp (setopt agent-shell-write-inhibit-minor-modes '(aggressive-indent-mode)) #+end_src

*** Keeping the system awake during long turns

Long agent turns can outlast the system idle-sleep timeout, suspending the machine (and the agent) before the turn completes. On Emacs 31.1 or later, =agent-shell-inhibit-system-sleep= (enabled by default) keeps the system awake for the duration of each turn and releases the block once the turn finishes, so the system is only kept awake while there is work in progress (the display is still allowed to blank). This relies on the built-in [[https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/system-sleep.el][=system-sleep=]] library and has no effect on earlier Emacs versions. It does not prevent "hard" sleep such as closing a laptop lid.

To turn it off:

#+begin_src emacs-lisp (setopt agent-shell-inhibit-system-sleep nil) #+end_src

All of the above settings can be applied on a per-project basis using [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Directory-Variables.html][directory-local variables]].

** Key bindings

  • =RET= - Submits prompt.

  • =M-J= - Iserts newline.

  • =C-c C-c= - Interrupt current agent operation

  • =TAB and Shift-TAB= - Navigate interactive elements

    To customize =RET= binding behaviour, you can use something like:

    #+begin_src emacs-lisp :lexical no (use-package agent-shell :bind (:map agent-shell-mode-map ("RET" . newline) ("M-RET" . shell-maker-submit))) #+end_src

    Or if you prefer C-c C-c to send and C-c C-k to interrupt, use the following:

    #+begin_src emacs-lisp :lexical no (use-package agent-shell :bind (:map agent-shell-mode-map ("RET" . newline) ("C-c C-c" . shell-maker-submit) ("C-c C-k" . agent-shell-interrupt))) #+end_src

*** Session controls

When the active agent advertises the corresponding session option, you can switch it from the shell buffer:

  • =C-c C-v= - Set model.
  • =C-c C-m= - Set session mode.
  • =C-c C-t= - Set thought level (reasoning effort).
  • =C-= - Cycle session mode.

The current selections are shown in the header right after the agent name; click any segment to open a popup menu. The thought level segment only appears for models that expose it (e.g. Claude Sonnet/Opus with effort levels; Codex's reasoning_effort).

From the viewport (=agent-shell-viewport-view-mode= / =agent-shell-viewport-edit-mode=), the same controls are bound to:

  • View mode: =v= (model), =s= (mode), =t= (thought level).
  • Edit mode: =C-c C-v=, =C-c C-m=, =C-c C-t=.

*** Evil Evil users may want to rebind RET for inserting a new line in =insert mode= and sending the prompt in =normal mode=.

Also, when viewing diffs (before accepting changes) it may be annoying having to enter =insert mode= to send keys (y/n/p/q/etc). If this is your case, you can make these buffers start in Emacs mode (you can always go to Evil modes if you need to with C-z). #+begin_src emacs-lisp (use-package agent-shell :config ;; Evil state-specific RET behavior: insert mode = newline, normal mode = send (evil-define-key 'insert agent-shell-mode-map (kbd "RET") #'newline) (evil-define-key 'normal agent-shell-mode-map (kbd "RET") #'comint-send-input)

;; Configure *agent-shell-diff* buffers to start in Emacs state
(add-hook 'diff-mode-hook
    (lambda ()
      (when (string-match-p "\\*agent-shell-diff\\*" (buffer-name))
	(evil-emacs-state)))))

Please read through this section before filing issues or feature requests. I won't be able to help unless I have enough information to help. This section shows how to get the details I need.

  • Versions: What version of =agent-shell=, =acp.el=, the ACP package (e.g. =claude-code-acp=), and the agent CLI (e.g. =claude=, =gemini=) are you running?
  • Steps to reproduce: What exact steps lead to the issue? Be specific about what you did and in what order.
  • ACP traffic: See [[https://github.com/xenodium/agent-shell?tab=readme-ov-file#how-do-i-viewget-agent-client-protocol-traffic][how to get ACP traffic]] above. This is the most useful piece of information for diagnosing issues.
  • Screenshots: A screenshot helps correlate what you see with the protocol data.
  • Your agent-shell config: Share any relevant =agent-shell= variable settings from your Emacs config.
  • Profiling data (for performance issues): Use =M-x profiler-start=, reproduce the issue, then =M-x profiler-report= (and =M-x profiler-stop=). Share the report.
  • FAQ

** Why doesn't =agent-shell= offer all slash commands/skills available in CLI agent?

=agent-shell= can only offer the slash commands/skills advertised by the agent via [[https://agentclientprotocol.com][Agent Client Protocol]]. To view what's exposed by your agent, expand the "Available /commands" section. Is the command you're after missing? Please consider filing a feature-request with the respective agent (ie. Gemini CLI) or their ACP layer (claude-code-acp).

[[file:slash-commands.png]]

** Can you add support for another agent?

Does the agent support ACP ([[https://agentclientprotocol.com][Agent Client Protocol]])? If so, =agent-shell= can likely support this agent. Some agents have ACP support built-in (like [[https://github.com/google-gemini/gemini-cli][gemini-cli]]). Others require a separate ACP package (like [[https://github.com/zed-industries/claude-code-acp][claude-code-acp]] for [[https://github.com/anthropics/claude-code][claude-code]]). When filing a feature request to add a new agent, please include a link to the project supporting [[https://agentclientprotocol.com][Agent Client Protocol]] (built-in or otherwise).

Agents without ACP support are out of scope for integrating with =agent-shell=. Having said that, if you do build an ACP layer like =claude-agent-acp=, then =agent-shell= can work with it.

** =agent-shell= not behaving as expected?

Could be the agent itself missing an [[https://agentclientprotocol.com][Agent Client Protocol]] feature, =agent-shell= missing the feature, or both :) So which one is it? It's hard to tell unless we look at [[https://agentclientprotocol.com][Agent Client Protocol]] traffic between the two.

** Is shx supported? No. There are reports that [[https://github.com/xenodium/agent-shell/issues/543][it does not work]] with agent-shell. ** How do I view/get [[https://agentclientprotocol.com][Agent Client Protocol]] traffic?

  1. =M-x agent-shell-toggle-logging= (make sure logging is ON).
  2. Reproduce the issue
  3. =M-x agent-shell-view-traffic=

Browse through traffic and see if you can spot the issue. For example, if you see a request sent by the agent asking for user permission, but =agent-shell= isn't surfacing this permission, it looks like perhaps =agent-shell= is missing a feature.

For example, here's what a [[https://agentclientprotocol.com/protocol/schema#session%2Frequest-permission][session/request_permission]] request would look like from the traffic viewer.

[[file:traffic.png]]

Sometimes including a traffic screenshot in an issue is enough. Other times including the full traffic is needed. From the traffic viewer, you can =M-x acp-traffic-save-to= to save as =.traffic=.

** Where should I file bug or feature request?

*** Agent issues or feature requests

If you're able to determine the agent is missing a feature (or a bug is present) in their [[https://agentclientprotocol.com][Agent Client Protocol]] implementation, please file an issue directly with the agent folks. For example:

*** =agent-shell= issues or feature requests

Alternatively, if you noticed =agent-shell= is missing a feature (or has a bug), please [[https://github.com/xenodium/agent-shell/issues][file an agent-shell issue]].

*** Not sure where to file an issue?

File [[https://github.com/xenodium/agent-shell/issues][in agent-shell]], but please try to provide details, so I can determine whether =agent-shell= or the agent itself needs work. Traffic data would be very useful here. Provide a screenshot or a .traffic file if you think it'll help. See [[https://github.com/xenodium/agent-shell?tab=readme-ov-file#how-do-i-viewget-agent-client-protocol-traffic][how to get ACP traffic]].
